FDA warns about UV lights to disinfect coronavirus and other germs

From CNN Health’s Maggie Fox

Lamps that use ultraviolet light to kill germs can inactivate coronavirus, but they are not all safe and it is not clear how good a job they do at killing the virus, the US Food and Drug Administration said Wednesday.

The FDA said ultraviolet-C (UVC) wavelengths are better than UVA and UVB light at destroying viruses, but UVC lamps still have their limits.

“The effectiveness of UVC lamps in inactivating the SARS-CoV-2 virus is unknown because there is limited published data about the wavelength, dose, and duration of UVC radiation required to inactivate the SARS-CoV-2 virus,” the FDA said in a newly posted statement.

 Plus the lamps only work in limited circumstances. 

“It is important to recognize that, generally, UVC cannot inactivate a virus or bacterium if it is not directly exposed to UVC. In other words, the virus or bacterium will not be inactivated if it is covered by dust or soil, embedded in porous surface or on the underside of a surface,” the FDA said. 

There’s been an explosion of products on offer to fight coronavirus, including germicidal lamps. The World Health Organization warns against trying to use them to disinfect human skin, including the hands.

In addition, some UVC lamps generate ozone, which can irritate airways.

“Some UVC lamps contain mercury. Because mercury is toxic even in small amounts, extreme caution is needed in cleaning a lamp that has broken and in disposing of the lamp," the FDA added.

Germany recorded 1,707 new cases of Covid-19 in the past 24 hours -- the highest number of daily infections since the end of April, according to the country's infectious diseases department, the Robert Koch Institute.

The last time the number of new cases was this high was on April 26, when the country registered 1,737 new infections, according to German public broadcaster ARD.

Germany saw its peak in new daily Covid-19 cases at the beginning of April, when more than 6,000 infections were reported in one day. In the following weeks, the number of cases fell significantly.

But the number of positive tests has been increasing since the end of July.

The US Food and Drug Administration said Wednesday it had authorized a new antigen test to diagnose coronavirus infection -- the third test of its kind to receive emergency use authorization from the agency.

The British-made LumiraDx test can analyze a sample within 12 minutes, the FDA said.

What are antigen tests: Unlike time-consuming PCR tests, antigen tests look for specific parts of a virus rather than multiplying any viral genetic material present.

How it works: The test requires a nasal swab and can give results right away, instead of having to be sent off for analysis. Health officials hope such tests can help the US ramp up coronavirus testing.

 “LumiraDx Platform is a novel, flexible, highly scalable and low cost rapid point-of-care test that will significantly contribute to our scaling up and expanding testing platforms for SARS-CoV-2. This technology has built-in digital connectivity, almost everything we hope for in new testing platforms coming to market,” Adm. Dr. Brett Giroir, the testing “czar” on the White House coronavirus task force, said in a statement.

Reliability: The FDA published data from company submission showing the test has 97.6% sensitivity, meaning it catches 97.6% of cases correctly, and 96.6% specificity, meaning it correctly rules out infection 96.6% of the time.

Mental and physical health issues dismissed at Australian hotel quarantine, inquiry hears

From CNN's Zehra Jafree and Helen Regan

Health officials in Australia's Victoria state allegedly refused requests for medication from people in pain, lost track of returning travelers and dismissed threats of suicide, an inquiry into Melbourne’s hotel quarantine system heard on Thursday.

The inquiry was launched amid allegations that a fresh coronavirus outbreak in the state of Victoria was sparked by some contracted workers not following protocols at hotels used to quarantine international arrivals.

A nurse contracted to work in three quarantine hotels, identified only as "Jen," told Thursday's hearing there were serious questions over the nursing staff’s training and experience to handle mental health issues among the returning travelers. 

Suicide threat allegedly dismissed: In one incident, Jen said she followed up with the Department of Health and Human Services -- which ran the quarantine program -- to see if they were aware of a situation in which a guest was threatening suicide.

“At that point a person who worked for DHHS told me that they had specifically called this guest in their room and told them that they need to stop threatening suicide just so they can get a cigarette,” she said at the hearing.

Jen said she tried to reach the guest via phone but couldn’t get through. When she went to check on the guest they were found to be unharmed but in an “anxious” state. 

The employment agency that contracted staff, Your Nursing Agency (YNA), denies the allegation that staff were not trained to deal with mental health issues, and said that all of the mental health nurses provided by YNA Mental health were certified.

Lost and ripped up documents: Jen said that inadequate record keeping by DHHS meant travelers were not being tracked properly and she resorted to using her own spreadsheet to document who was staying in the hotel.

In one instance, a family had been in quarantine for a week without being contacted for a welfare check, she said.  

“It was very obvious that DHHS were having a hard time of keeping track of who is in the hotel and when,” she told the inquiry. 

She said that she had made complaints after finding documents ripped up.

The inquiry on Thursday also heard testimony from a second nurse and a returning traveler. Hearings will continue this week.

Mystery surrounding source of New Zealand community cluster remains unsolved

Five new locally transmitted cases have been reported in New Zealand according to the country's Director-General of Health Dr. Ashley Bloomfield on Thursday.

"The source of this current larger community cluster still remains open," he said.

Mystery over outbreak: 80 Covid-19 infections have been linked to the latest community outbreak, but authorities are investigating two cases where they have found no link to the original cluster in Auckland.

One of the cases of unknown origin is a maintenance worker from a managed isolation facility at a hotel in Auckland. The other was thought to have links to the original cluster but is now under investigation.

Health officials in Auckland have found a link to another positive case who used the same elevator as the maintenance worker.

Separately, the virus levels detected in the Americold workplace environment -- an American temperature-controlled warehouse company that has had several employees test positive -- and on packaging there was too low to be tested for genome sequencing. 

"At the border nationwide, 7,649 workers have been tested at the airport and ports, all of them so far coming back negative," New Zealand Health Minister Chris Hipkins said.

Almost all of the staff at the managed isolation facilities in Auckland have been tested -- 2,891 of 2,900 all tested negative barring the one maintenance worker.

Controversy over Australian PM's vaccine comments points to the next coronavirus nightmare

With one comment, Australian Prime Minister Scott Morrison managed to turn a positive coronavirus story into a public relations disaster, and highlighted the potential next nightmare of the pandemic: a fight over vaccines. 

Speaking about a plan to provide free coronavirus immunization to all Australians as soon as that is possible, Morrison said Wednesday that he would "expect it to be as mandatory as you could possibly make it," with some exemptions on medical grounds. 

His health minister, Karen Andrews, reiterated that line later, saying the government was "looking at it being a mandatory vaccine." But by Wednesday evening, Morrison was already backtracking, telling radio station 2GB that "it is not going to be compulsory to have the vaccine ... there are no compulsory vaccines in Australia."

Morrison's reversal came after his original comments had been seized on by anti-vaccination groups in Australia and around the world, many of which have long warned of supposed plans to force a coronavirus jab on people.

While his comments created something of an open goal for anti-vax campaigners, the scandal does point to the wider issue of "vaccine hesitancy," which the World Health Organization identified last year (before the coronavirus pandemic hit) as one of the top 10 threats to public health around the globe.

It should concern everyone. Without an effective coronavirus vaccine, there currently appears to be no other viable way to return to pre-pandemic normality.

Brazil’s President may extend emergency unemployment payments amid pandemic

Brazil’s President Jair Bolsonaro said on Wednesday he might extend emergency payments through the end of the year for the unemployed, but the payments will be at a lower rate than the current 600 reais ($108) a month. 

The latest official figures on unemployment show that a total of 8.9 million people lost their jobs as the coronavirus pandemic swept through Brazil -- representing the sharpest contraction on record for the country. 

Brazil's unemployment rate rose to 13.3% for the quarter ending in June.

Bolsonaro said continuing with 600 reais a month is not an option because it would plunge Brazil into debt, hurting the country's fiscal credibility.  

“This is not the people's money, this is indebtedness, and if the country becomes over-indebted, it ends up losing its credibility,” Bolsonaro said. 

Brazil’s Economy Ministry talked about decreasing the amount to 200 reais ($36) a month, Bolsonaro said, but the President said he thinks the amount is too low and suggested they strike a deal somewhere in the middle. 

“It is possible to reach a middle ground and we will seek to extend it for a few more months, perhaps until the end of the year,” Bolsonaro said.

Meanwhile, the economy minister Paulo Guedes said the economy is recovering in the shape of a Nike “swoosh.” 

"All the indicators show the drop was sudden, rough and strong, but Brazil is coming back,” he said.

On Wednesday, Brazil confirmed 49,298 new Covid-19 cases and 1,212 deaths in 24 hours. At least 111,100 people have died in Brazil from coronavirus and the total number of confirmed cases now stands at 3,456,652, according to the Health Ministry.

China says no hospitalized coronavirus patients have died in "almost four months" 

Chinese health officials have said that no patients hospitalized due to Covid-19 in China have died in "almost four months."

Guo Yanhong, an inspector of China's National Health Commission, lauded the Chinese strategy in containing the spread of the virus saying, "This is the strongest proof that China's experience, methods, and strategies in treating critical patients are valuable."

He made the comments at China's Joint Prevention and Control Mechanism of the State Council on Wednesday.

The last time a virus death was reported by the NHC was April 14, when one fatality in Hubei province was recorded, according to data on its website. 

Latest cases: On Wednesday, 22 imported cases and one locally transmitted asymptomatic infection were reported in the country, NHC figures showed. In addition, seven new imported cases were also recorded on Wednesday in the provinces of Jiangxi, Tianjin, Shanghai, Shandong, and Sichuan.
